- Abstract
- Households differ considerably in terms of the inflation they experience at any point in time. The main reasons for this are that prices (and thus price changes) differ from place to place and that households do not all buy the same products. Households adjust their purchases over time, but not enough to offset these differences.

- Abstract
- This paper studies the nature, evolution, and sources of inflation heterogeneity across households in France and Germany. Inflation differences are large and persistent. The two main sources of inflation heterogeneity are spatial differences in the prices paid for the same product and differences in the household-specific variety choice within a category. Income heterogeneity by itself is not a relevant determinant of inflation heterogeneity, but due to its correlation with household behaviour, a significant and timevarying inflation difference between income groups emerges. Substitution is strongly behaviour-driven and largely detached from the relative price. The dispersion of the household-level elasticity of substitution does not fully account for the heterogeneity of substitution behaviour. Substitution does not reduce the dispersion of inflation, confirming the central role of preference heterogeneity in inflation measurement.
